Zoe's Killer Vagina

AHS is at its scariest when the viewer doesn't exactly know what's happening. To whit – the moment in Coven's premiere when Zoe manifests her ability to kill sexual partners with. . . her vagina? The mechanics are unclear. The freshman witch later uses her skill for revenge, but nothing can rival her boyfriend's unexpected demise in the season premiere. Having sex for the first time is scary enough without a brain hemorrhage.
